Question

How I can use the intent to send the data to the second class?

I am doing this actually

Intent connectGetData = new Intent(Main.this, GetData.class);
startActivityForResult(connectGetData, REQUEST_GET_DATA); 

From Main.java activity I am calling the Getdata.java activity and I when come back I again get data using.

public void onActivityResult(int mRequestCode, int mResultCode, Intent mDataIntent) 

Please tell me how I can send data to other activity

Answer 1

You pass data along with the Intent using two mechanisms, depending on the needs of your application.

1. The data field, via Intent.setData(): This is a URI that you can use to indicate the location of a resource the new Activity may need to use
2. Extras, via Intent.putExtra(): You can attach as many extras to an Intent as you like to represent the data you need to pass (both forwards to the new Activity and backwards with the result). Extras can be any primitive or easily serializable object.
